Running from Corpus Christi to near Brownsville, Padre Island is the longest barrier island in the world. Up until the late 1950s, you could drive the entire 113 miles of the island if you had a vehicle with decent four-wheel drive. That option was blocked in 1957 when the Port Mansfield Cut was dredged. The waterway had been a dream of Laguna Madre locals for decades. Texas Standard commentator W.F. Strong tells us how the island was split and what was found.
